Promag Thompson Carbine Rifle Magazine Drum Black .45 ACP 40/rd

The Promag Thompson Carbine Rifle Magazine Drum Black .45 ACP has a 40-round capacity, making it an excellent choice for those who prioritize magazine capacity and reduced reload frequency during extended shooting sessions or training exercises. This magazine is specifically designed for the Auto-Ordnance Thompson .45 ACP carbine platform, ensuring compatibility and reliability.

Constructed from a proprietary DuPont Zytel-based polymer drum housing, this magazine features an injection-molded follower and a heat-treated stainless steel spring. This combination ensures reliable feeding of .45 ACP rounds while maintaining the expected weight distribution characteristics of drum magazines. The Zytel polymer offers impact resistance and environmental durability, while the stainless spring steel resists corrosion during extended storage or humid conditions.

This magazine is perfect for carbine operators, firearms trainers, and enthusiasts of the Thompson platform who require extended magazine capacity for precision rifle courses, three-gun competitions, or historical platform shooting. The 40-round capacity minimizes transition time between magazines during sustained fire drills, making it an excellent choice for high-round-count training sessions.
